Blink is one of the few "new" episodes I've seen. At which point I decided I wanted to start at the beginning, the original series. As a kid, I had watched Doctors 4, 5 and 6. I've been working through what Netflix has on DVD--have a couple episodes left of Doctor #2.
We did this several years ago. H had never watched Doctor Who back when it was on PBS in the 80s. I had watched several seasons with my older brothers. So after the first few episodes where he was like "WTF? Trashcans as the ultimate enemy of the universe?" I was like "We are watching all of the old serials."
Everyone loves 4. I re-discovered my love of 5 and thoroughly enjoyed 3. 1 and 2 are ok. I really did not like 6. There weren't as many discs of 7 when we did this, so I can't really say. I was pretty meh. And I wish we'd seen more of 8 than just the movie. I know he's done a shitton of audio adventures and such, but I haven't gotten into those. Yet.
